[SOLVED] slackpokg upgrade to current

ngc457 · 02-02-2010, 12:30 PM

I just upgraded to current using slackpkg and before rebooting I was making some necessary changes to lilo.conf.

Basically I changed all instances of /hd* to /sd* namely:

boot=/dev/sda
root=/dev/sda1

However, when I run 'lilo -v -b /dev/hda' I get a:

Fatal: Illegal 'root=' specification :/dev/sda1

Help!

Can you list the sda layout ... ? (Can you access /dev/sda1)

Code:

fdisk -l /dev/sda
# or even...
fdisk -l /dev/sda1

I just did that yesterday and had a heck of a time. What I did that finally worked was use mkinitrd add the initrd.gz file to lilo.conf after the image line, then (hopefully this wont be a problem for you, but) I rebooted to which I had to mount /dev/sda# on /mnt, then exit, then it finally booted into the hd, then you will be able to rerun lilo to fix it.

<Edit> Just thinking about it, while it's running and all, better get a second opinion from someone who knows more first...

Hi,
Robby Workman wrote up a howto that should provide some help.

There is no /dev/sda yet. I started all this using Slack 13 which is using /hd*, after upgrading I'm changing all instances of /hd* to /sd* in fstab and lilo.conf to avoid a kernel panic upon reboot.

That's what I'm working from.

Is this my problem? I started with S13. (default install)

* If you are using one of the generic kernels (requiring an initrd), then use the sd* name for the root device when creating the image.

Other than this step I followed his instructions.

Use the new designation for root (-r /dev/sda1) with the mkinitrd command.
Except for that change, it will be the same command you ran before.

For the root= line in lilo.conf, you'll have to leave it as hda1 for now.

Or you could use one of:
root=current
root="LABEL=the-disk-label"
root="UUID=really-long-UUID-string"

(the quotes are needed if you use UUID or LABEL, see "man lilo.conf")

If Robby's way doesn't work you could try booting with the cd/dvd, mount /, chroot to it, edit lilo.conf and running lilo.

What worked for me was to boot from the Slackware 13 install disk and continue until after selection of a keyboard and you have a root login. Then:
'mkdir /mnt/tmp'
'mount /dev/hda1 /mnt/tmp'
'chroot /mnt/tmp'
If using an initrd then, 'cd /boot' and run mkinitrd specifying -r /dev/sda1
Edit /etc/lilo.conf so that "boot=/dev/hda" in the global section and "root=/dev/hda1" in the partition config section. Also check that "image=<your new kernel>" and you have an "initrd=/boot/initrd.gz".
'exit'
'/mnt/tmp/lilo -r /mnt/tmp' - lilo should run without error
Now you should be able to boot using the root=/dev/sda1 option, so you can fix up lilo.conf and rerun lilo.

This worked. Hope this fixes my Intel video woes. :-)

Thanks.
